Dyno + cams + white smoke?
So I recently installed stage 2 hi tech cams in my 03 mustang. Prior to cams I dyno'd 252wrhp and 297tq. After cams, I gain 44wrhp and did 297wrhp but tq stayed similar. I'm happy with results, seeing it's untuned for the cams (has bama tuner on it for other mods) and was running a bit rich. My concern however is on wot higher rpm there is white smoke coming from the exhaust (a good amount, but doesn't exactly smell sweet according to a friend who was following me). On idle or regular driving, it doesn't do it. I've checked both oil and coolant and both are just as they should be. Also, never did this before cam install. What could it be? If it makes any difference, I changed the oil after cam swap and used higher zinc containing oil.

If your car is blowing White smoke, this means you're burning coolant. The first place I would look is the head gasket. Make sure you don't have a small rip or something along those lines. Before ripping the car apart, I would also make sure the smoke is White. Different colors could mean running rich, burning oil, just having no cats etc...
I hope this helps. Please let me know if you have any questions or need some further assistance!

It's only blowing smoke under load and high rpm. Idling or regular driving it's just fine. It's hard to tell the color seeing it only does it while driving, looks kinda white but dark colored. Could be bluish, idk. Car doesn't have cats. It's got shorty headers x pipe and magnaflow mufflers. I've been checking coolant level and oil and both are just fine. My coolant level hasn't dropped a single bit. Ran rich on the dyno but not extremely bad. A/F ratio was about 11.

Keep an eye on the Coolant and Oil, if anything seems out of the ordinary let us know!

Well just an update on the problem. Turns out to be something completely unexpected. The gasket on the base of my short throw shifter basically blew out and at higher speeds trans oil would leak out onto the exhaust, thus burning a white color. Easy fix luckily!
